  • Light emitting device including adhesion layer
    Patent number: 7550777
    Abstract: A light emitting device has a light emitting element and an adhesion layer to bond the light emitting element to a mounting member. The adhesion layer is of inorganic material particles and a transparent inorganic binding layer to be formed between the neighboring inorganic material particles, and the inorganic material particles are substantially connected with each other in the adhesion layer. Another light emitting device has a light emitting element and a phosphor layer that radiates fluorescent light while being excited by light emitted from the light emitting element. The phosphor layer is of phosphor particles and transparent inorganic binding layer to be formed between the neighboring phosphor particles.
